By 1932 the neutron particle was recognized and added to the nuclear mix ... trigger a similar reaction in nearby atoms, creating a self-sustaining chain reaction,” writes Ms. Santos.

A Brief History Nuclear power has had its share of ups and downs since its inception. The idea of harnessing the energy from ...

In simple terms, that assertion is correct, but for those with an expertise in the field, the longer answer to who did it ...

Learn more here. In 1942, the Manhattan Project needed to create a chain reaction—a crucial step toward proving that it would be possible to make an atomic bomb. The scientists achieved this sustained ...

They are all "subcritical," meaning that they simulate conditions inside a nuclear weapon without triggering a nuclear chain reaction. That runaway chain reaction, in which some atoms split apart and ...

Scientists have discovered that a piece of uranium extracted from an African mine is a two billion-year-old natural nuclear reactor they're calling Oklo.

The U.S. hasn't tested a nuclear weapon in decades, and since the 1990s has used simulations and experiments to verify they're working properly. NPR was granted a rare look at how they do it.

By the end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be possible. When slowed down and controlled in a "uranium machine" (nuclear ...
